Finlarig Castle

A short walk uphill from Killin brings you to the crumbling remains of Finlarig Castle, a 17th-century stronghold that's seen better days but commands proper views across Loch Tay. The castle itself is roofless and overgrown, which means it's free to explore whenever you fancy - there's no entrance fee or opening hours to worry about. You'll find the ruins open to the elements, so decent footwear matters and a dry day helps.

What makes the walk worthwhile isn't the castle architecture alone - it's the setting. The Tay valley spreads out below, and on a clear day the light hits the loch in a way that makes the short climb feel earned. The site has real bones to it: you can pick out where the kitchen was, trace the walls, imagine the place when it had a roof and glass in the windows. It takes about 40 minutes up and down, depending on pace and how long you linger.

If you're staying at Loch Tay Highland Lodges nearby, this combines nicely with a morning or afternoon exploring the town itself. History types will appreciate the 1600s-era story, though it's not dramatic ruins - more intimate than imposing. The walk suits families with older kids who won't mind a muddy path. Younger children might find the actual castle underwhelming once they realise there's not much left to climb on. Worth doing if you're in the area, but don't rearrange your itinerary for it.
